location map for members

I tested the modules views, gmap, location. Together they will give you a location view of users. Each user can
manually click on the google map to enter their lat/long and it will save it. Then the map of location users will display markers for all users who manually entered their location (by clicking on the map).

Will this be sufficient?

You will need a google api key for this domain.

I can get together with the admin of the site and do the configuration if desired.

If you would rather have something else, let me know.
